Does anyone know anything about the GM 427 Crate motor... a guy is tryin to sell me one for $600 and all it needs it a water pump but i dont know much about gm crate motors....i dont have the #s off of it yet but i was just wondering if i could get a guess-timate on hp and ftlbs stock and what kinda of stroker can i make from it....thx...

If there's no paperwork, see if he'll let you pull a valve cover and get the head casting number. Depending on when it was built, it could be a standard deck or a tall deck block also. See if there's a block number on the rear of the block and a number on the deck of the passenger side just in front of the head.

When you have the numbers, PM me with them along with the guys phone number and address. Then call him and tell him you're not interested. I'll take it from there for you to keep you from messin' with it.

And if it says "hi perf pass" cast into the side of the block, don't be overly impressed. Most, if not all, stock non-high-performance big-blocks had that on them. It DOES mean that it's not a tall-deck block, but it's not some kind of special rare super-duper race block or anything like that.
